This invention relates to refrigerating apparatus, particularly todevices such as hinges, latches, escutcheons, and the l ke Which areordinarily associated with the doors of refrigerating cabinets.

It is among the objects of the invention to provide an improvedconstruction of hinge or the like which is economical to manufacture,which has an attractive appearance and 10, which is stronger and moredurable than devices of' this sort heretofore used.

It is another object of this invention to provide a hinge or similardevice which may be attached tohighly finished or frangible surfaceswithout injuring the finish of the surface. It is also an object of thisinvention to provide a pressed metal hinge or similar device which iseconomical to manufacture and which has the rich, heavy appearance ofcast metal devices of this character and a strength and durabilitysuperior to cast devices.

Further objects and advantages of the present invention will be apparentfrom the following description, reference being had to the accompanyingdrawings, wherein a preferred form of embodiment of the presentinvention is clearly shown.

In the drawings 7 Fig. 1 is a perspective view of a hinge; Fig. 2 is aView of a hinge partly in longitudinal section and partly in elevation,and Fig. 3 is a section on the line 33 of Fig. 1. Referring to thedrawings, 10 indlcates a door of a refrigerating cabinet which 1ssupported on a jamb 11 by hinges generally denoted by 12. The doorincludes a metal cover having a frangible finish thereon and formed toprovide the front surface 13 and edge surface 14. The hinge chosen forillustration of the present invention has a butt member 15 attached tothe jamb and a strap member 16 suitably pivoted to the butt member inthe usual manner and attached to the door; For the sake of appearance itis desirable to have the strap member in contact with both surfaces ofthe door and to this end it is provided with an L-shaped edge whichcontacts with both surfaces.

Hinges of this character as heretofore con- 1927. Serial No. 209,559.

metal having'an outer curved surface 20v which presents a rich andpleasing appearance and a fiat surface to be clamped against the door.The fiat surface has a large area which distributes the clamping forceuniformly. over the contacting surface, which results in a low pressurebeing applied to the base or frangible surface. These hinges have beenobjectionable for the reason that in cases where the hinge is in contactwith both the face and edge surface of the door, unless the strap memberis made so massive as to be objectionable from the standpoint of costand appearance, the strap member is particularly weak at the pointopposite the corner 21 and frequently breaks at this point when the dooris swung wide open and suddenly stopped by the hinge reaching the limitof its travel. I

I remedy the above defects by providing a hinge having a strap ofpressed metal which on the outside may have an appearance identical withthat of previously known cast hinges, the strap member beingappropriately curved as shown in the sectional views. The curvature ofthe strap provides great strength and results in having the strap incontact with the surface of the door at its edges only. In order toprovide great strength at the portion of the strap which passes aroundthe corner of the door and also to provide an edge which will not injurethe finish of the door surface, I provide a reenforcing rim or flange22, integral with the strap and continuous thr'uout the length of theedge which contacts withthe door. This flangeis formed preferably byturning the edges of the strap in along its entire len th. Thus thestrap has in effect an L-shaped e go, one leg of which contacts with thesurface of the door and both legs of which are provided with areenforcing and surface protecting bend, flange or rim. The fact thatthe rim is continuous around the corner makes an exceedingly stronghinge.

It has been found that the best results are obtained when the rim makescontact with the surface of the door at a very slight acute angle,preferably about 3.
